Answer: 65
Step-by-step explanation:
P = 2L + 2w <---- formula for perimeter
26 = 2L + 2w <--- original perimeter is 26
13 = L + w <--- divides everything by 2
32.5 = 2.5L + 2.5w <-- scale factor of 2.5; those are the NEW length and width
Multiplying both sides by 2, the new perimeter is 65;

Write an exponential function to model the following situation.
A population of 130,000 grows 3% per year for 16 years.
How much will the popluation be after 16 years?
Write an exponential function in terms of x.
y=10
Answer:
y = 130,000(1.03)ˣ
Step-by-step explanation:
The general form of an exponetial function is y = abˣ, where a is the initial value (when x = 0), and b is the multiplier (the growth or decay factor). Here, we start with a population of 130,000, so our initial value a = 130,000. A growth of 3% each year represents a growth factor of 1.03, so after x years, the population y should be y = 130,000(1.03)ˣ.
The exponential function in terms of x and y is y = 130,000(1.03)ˣ
What is an exponential function ?The exponential function is a mathematical function denoted by
y = abˣ
where a is the initial value (when x = 0)
and b is the multiplier (the growth or decay factor).
population starts from 130,000, so
Initial value a = 130,000.
A growth of 3% each year represents a growth factor of 1.03,
so after x years, the population y should be
y = 130,000(1.03)ˣ
Therefore , The exponential function in terms of x and y is y = 130,000(1.03)ˣ

Answer:
I'll help you with this so reflections is not hard.
For reflect over x-axis you need to switch the sign on Y. formula for points like this is (x,y). An example is reflect (2,4) over the x-axis. you just change the sign of y making the answer (2,-4).
For reflect over y-axis you change the sign of X.For example reflect over the y-axis (3,7) all you have to do is change the sign of X which leaves you with the answer of (-3,7).
sign is basically + or - if need to know.

6.Kelly has been training to run across the country. On the first day, she ran 4 miles, the
second day, she ran 12 miles, and the third day, she ran 36 miles.
a) Write an equation that models Kelly's situation?
Answer:
D= d₁ + d₂ + d₃ : where D is total distance covered in the training.
Step-by-step explanation:
Let this equation model the total distance covered in the training.
Let the total distance covered in the training to be: -------D
Let the distance covered in 1st day be ----------d₁ = 4 miles
Let the distance covered in 2nd day be ----------d₂= 12 miles
Let the distance covered in 3rd day be ----------d₃ = 36 miles
D= d₁ + d₂ + d₃
D= 4 + 12 + 36
D= 52 miles

Hi there! I'm here to help. :)
Okay, so here you are solving for x. To solve for x, you must get it alone on one side of the equal sign. As we can see, it is not alone, and it is with 1 1/4 on the left side of the equal sign.
To get it alone, we need to subtract 1 1/4 from both sides. However, to subtract fractions, we need to make sure they have the same denominator. Looking at the fractions, we can see that they have two different denominators.
Begin by converting both fractions into improper fractions:
1 1/4 = 5/4
3 1/2 = 7/2
So now our equation looks like this: x + 5/4 = 7/2
Now we need to make it to where we our fractions have the same denominator.
Our current denominators are 4 and 2. The LCM (lowest common multiple) of 4 and 2 is 4, so you leave 5/4 as it is (because it's denominator is already 4) and you change 7/2.
Multiply 2 * 2 to make the denominator 4 in 7/2, but whatever you do to the denominator, you MUST do to the numerator. So multiply 7 * 2 = 14. Now your fraction looks like this: 14/4
Now we have:
1 1/4 = 5/4
3 1/2 = 14/4
Our denominators are the same now! Now here comes the easy part: We subtract! Do 3 1/2 - 1 1/4, or, 14/4 - 5/4. To subtract fractions, simply subtract the numerators and leave the denominators as is. 14 - 5 = 9, so 14/4 - 5/4 = 9/4.
Now our equation looks like this:
x = 9/4
LASTLY: All of your options are mixed numbers, so convert this improper fraction back into a mixed number. 9/4 = 2 1/4.
So, x = 2 1/4. :)
Joe's cell phone cost him $21 per month plus $3 for every 1GB downloaded. What is the limit to the number of GBs he can download to stay within his monthly budget of $30?
Answer:
3GB’s you just add 21 to 3 and keep adding 3 until you reach 30
21+3=24 24+3=27 27+3=30
Step-by-step explanation:
joe can only use 3gb of data . bill is 21
21+9+30
1gb=3
3*9=9
3(3)+21=30
3×3=$9
$21+9= $30
he can download up to 3 gbs anymore and he'll go over budget.
Rewrite this expression using the distributive property.
(3x2 + 4x-7)(x-2)
Answer:
D
Step-by-step explanation:
Each factor on the right has to be multiplied by the equation on the left and then you add them.
The expression (3x² + 4x - 7) ( x- 2) can be rewritten as 3x³- 2x²- 15x + 14.
To rewrite the expression (3x² + 4x - 7) ( x- 2) using the distributive property, we need to distribute each term in the first polynomial to each term in the alternate polynomial.
(3x² + 4x - 7) ( x- 2)
= 3x²( x- 2) + 4x( x- 2)- 7( x- 2)
Now, distribute each term
= 3x³- 6x²+ 4x²- 8x- 7x + 14
Combine like terms
= 3x³- 2x²- 15x + 14
Thus, using the distributive property, the expression (3x² + 4x - 7) ( x- 2) can be rewritten as 3x³- 2x²- 15x + 14.
